Beschreibung:
Enoyl reductase (ENR), an enzyme involved in fatty acid biosynthesis, is the target for antibacterial diazaborines and the front-line antituberculosis drug isoniazid. Analysis of the structures of complexes of Escherichia coli ENR with nicotinamide adenine dinucleotide and either thienodiazaborine or benzodiazaborine revealed the formation of a covalent bond between the 2' hydroxyl of the nicotinamide ribose and a boron atom in the drugs to generate a tight, noncovalently bound bisubstrate analog. This analysis has implications for the structure-based design of inhibitors of ENR, and similarities to other oxidoreductases suggest that mimicking this molecular linkage may have generic applications in other areas of medicinal chemistry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baldock, C -- Rafferty, J B -- Sedelnikova, S E -- Baker, P J -- Stuitje, A R -- Slabas, A R -- Hawkes, T R -- Rice, D W -- New York, N.Y. -- Science. 1996 Dec 20;274(5295):2107-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Krebs Institute for Biomolecular Research, Department of Molecular Biology and Biotechnology, University of Sheffield, Sheffield S10 2TN, UK.
